I think reterz is right about Rent-A-Car through Hertz as me to believe in them. I think everyone should be aware about the hertz reputation as it is available worldwide and people recommend them as best among the others. Even so many others car rental services providers like Enterprise Rent A car, Avis Rent A Car, Payless Car Rental, tripntourpackages. So here are few of top service providers available in Canada but, rest is up to you. So these are few and you can choose any of them.
